The TBA stands for Totally Botrytis Affected (versus the German Trockenbeerenauslese).

Light golden in color with no real signs of aging yet. Lots of Botrytis on the nose along with honey and some hints of light fruits (like a salad cup). On the palate, the same as the nose, but more botrytis and a mouthfeel that is more sauternes than the thickness of icewine, though it is still a bit thick. Lots of acidity though to break through the wine at the end so it ends of about as clean as any icewine has a right to. Different and interesting but not necessarily better than a typical icewine. About $27 per half bottle so this was not too painful as the world of dessert rieslings go.
